CHART FOR SIGNAL SYSTEMS.

Application led September 12, 1924:. Serial No. 737,227.

This invention relates to charts, and particularly to a chart to be usedin connection with a signal system using a plurality of dierent coloredlights which are flashed in various combinations, and has for an objectto provide a means for quickly indicating the individual being called.

With the foregoing and other objects in View, I have devis-ed the chartillustrated in the accompanying drawing forming a part of thisspecification, similar reference characters being employed throughoutthe various figures to indicate corresponding elements. In this drawing,

Fig. l is a view of my improved chart showing how it is laid out for asystem employing siX different lights of different colors, and

Fig. 2 is a similar view showing a layout for a system employing threedifferent colors of lights only.

In this type of signal systems there are as a rule a plurality ofstations ,located at different points desired, and each station has aset of lights including one light of each color to be used, the set oflights being the same for each station, Aand the signals are made byflashing these different colored lights in different orders orcombinations from a central control station. For example, th-e controlstation may be at the telephone exchange in a department store orfactory to be operated by the exchange operator, and when any yemployeenotices his signal being flashed he may call this operator and learn whowishes to get in communication with him. 0r if another employee noticeshis signal and knows where the employee is whose signal is being flashedhe may notify him that he is wanted. In the particular system for whichthis chart is designed the lights are flashed in sets of either one ortwo colors. If a single color is used for the signal it is flashed inthree dierent ways, that is, a single flash with a considerable intervalbetween any two flashes, two flashes with an interval between the secondand third flash twice the interval between the first and second flashes,or three comparatively rapid flashes of the same lamp equally spaced. Ifa Combination of two differ-ent colors are used the signal comprises oneflash of one color fol lolwed by two flashes of the second color, allVof the fasl'les having. however, the time interval between them.fllicniffo,`

first or single fiash may be used as a key for indicating whom is beingcall-ed by any particular signal.

My improved chart, an example of which is illustrated in theaccompanying drawing, employs this principle. Referring to Fig. l. thechart comprises a plurality of bars l0 preferably arranged horizontallyand one above the other, although, of course different arrangements maybe employed if desired, and each bar is of a different color, one barcorresponding to each of the differently colored lights employed at thevarious stations of the signal system. In the present case each stationhas six lights colored white, green, yellow, blue, red and purple, andthere is a bar l0 for each one of these light-s and colored the samecolor as its corresponding light. Thus on the chart bar No. l is white,bar No. 2 is green, bar No. 3 is yellow, bar No. l is blue, bar No. 5 isred and bar No. 6 is purple, and the surface shading on these bars is`made Yto indicate these colors. Each bar has associated with it aplurality of indications of different colors, there being an indicationfor each color of light used in the system and arranged with respect tothe bar in the same order that they are arranged at the station. Thusreferring to bar No. l the indications ll correspond to the signal lampsat the various stations. are of the same color as these lamps and arearranged in the same order, and to more nearly simulate the couditionsat the stations they are preferably made of an outline corresponding tothe shape of an electric light bulb, and these indications areexactly'the same for all of the bars above mentioned. Thus for each barlO the light indication No. l is white, No.' 2 green, No. 3 yellow, No.l blue, No. 5 red and No. 6 purple, and this is the arrangement oflights at the signa-l stations.

Each bar 10 has associated with it identificafion means for indicatingwhom is being. called by any particular signal. Thus associated witheach bar lO is aseries nf columns l2, there being a column in alignnientwith each light indication ll, each column in the present case extendingin a vertical line immediately beneath its particular light indication,and located in these columns are indications to represent the second orsecond and third flashes of the signal. These indications take differentably small er ci? :terms tut are prefs llO llO

`= be flashed in the signal.

the same color as the lights being flashed with which they correspond.Thus for eX- ainple, in any column 12 under light No. 2 or the greenlight, these indications will also be green, and in the column under theyellow light they will be yellow and so on, and the number of thesecolored indications for any given signal will correspond to the numberof times that particular light will Thus the horizontal bars 10correspond to or represent the first or single flash of the signal andthe indications 13 correspond to or represent the second or second andthird flashes in the signal, and located at one side of the columns 12are identification marks corresponding to the various signals. Theseidentification marks may be numbers as indicated at 14e or they may bethe names of the various employees as indicated at 15.

The chart is used as follows: In identifying any signal which is beingflashed we first note the single flash in the signal and then go to thebar 1() having the correspondingcolor. Thus if the signal is one whiteand two green flashes we first go to bar 1 which is the white bar. Vilethen go down the column 12 under the green light No. 2 and we note thatthe t-wo green indications 13 are opposite No. 4 in the left hand column14. Thus employee No. l is the one that is being called or Mr. Jones.Similarly if the first or single flash is blue and the other two white,the single blue flash will take us firstto bar No. l and under thecolumn corresponding to the white light No. 1 we find two indicationsopposite No. 30, and so on for each color combination throughout theentire system. As indicated above, however, some of the signals may bemade on a single lamp, as for instance where the signal comprises asingle white flash with a considerable interval between successiveflashes, or two white flashes with a short and a long interval, or threewhite flashes with equal intervals. In these signals we go to the bar 10corresponding with the color of the light flashed the same as in theother signals and find the corresponding indications under the light 11corresponding to the same color. Thus a signal of one white flash issignal No. 1, two white flashes No. 2, three white flashes No. 3, or onered flash is signal No. 33 under bar 5, two red flashes signal No. 34under bar 5 and three red flashes signal No. 35 under bar 5, and so onthroughout the system.

It will thus be apparent from Fig. 1 that in a system using siX lightsi8 different si g'- nals may be given using not more than two differentcolors in any signal, and that any signal may be easily and quicklyidentified by first locating the bar 10 corresponding to the singleflash and then locating the indications 13 for the remainder of thesignal under the corresponding light on that bar. This same principleobviously may be einployed for systems having other than su: lights. Forinstance, in Fig. 2 a card is illustrated employing this principle for asystem having three different lights only, in the example shown, white,blue and red. The principle, however, is exactly the saine as in thehrst form, there being a bar 10 colored to correspond with each of thelights, light indication 11 for each bar and also corresponding with thelights, and the indications i3 with the identification marks 14 and 15the same as in the first figure.

Having thus set forth the nature of my invention, what I claim is:
